Important: set yourself a calendar reminder, oh, a week from now to
turn
both options back on. I'm just guessing that this dumpster fire will get
sorted out before then, and you want to reenable it.
The first link you sent
https://discourse.mozilla.org/t/certificate-issue-causing-add-ons-to-be-d...
has a workaround that doesn't have this drawback:
Firefox Preferences -> Privacy & Security -> Allow Firefox to install
and run studies.
Undo this after restarting FF.
YMMV, but it worked for me.
